DISCLAIMER: I take no responsibility for damage to your instrument. The name of the game here is 'carefully' and 'gently.' Please take these steps slowly and deliberately. Make sure to read through the whole thing before starting this project.
I was pleased with the outcome even on my first try.... this was my second. I decided to do this because I capo so much that my frets themselves became dented. I also had terrible gouges in the fretboard itself from years of playing. These fretboard gouges do not affect the playability of the guitar, they are just ugly. My first refretting attempt was on a guitar that was already unplayable, so if I messed it up it didn't matter. Happily, it worked fine and I now have an old friend back!
You can obtain fret wire in many different sizes and radius online or at your local guitar repair shop. I made the switch to stainless steel fret wire instead of nickle. Stainless steel is much harder and less likely to wear down and get dents. I used this website. http://www.warmoth.com/supplies/supplies.cfm?fuseaction=fretwire Good luck.
Step 1: Remove the Frets
I used a soldering iron to heat the metal fret. This melts the glue in the fret slot and starts to let the fret go. Some guitars will have glue... some won't. But if there is glue you will notice it starting to bubble up from under the fret. Try not to let it get hot enough to burn your fret board.
Take a pocket knife, or something similar to gently pry the fret from the board. This is fairly easy to do... just go slowly. If you remove the fret to quickly without enough heating, the fretboard will chip. A little bit of chipping is normal... but try to keep it to a minimum. Really though, go slowly. Take your time. You love your instrument don't you?
Remember: The frets will be hot from the soldering iron so have pliers on hand to grab the removed fret. Place hot fret in a bowl of water or something so it can cool before you dispose of it.
Once completed I used a very light sand paper to remove some dirt & crud left over from pulling the frets.
Step 2: Clean Fret Slots
Step 3: Preparing the Gouges
Take a razor and make a series of slices into the fret board gouges you want to fill. Make fairly deep cuts and a whole bunch of slices right next to each other. Cut the entire length of each gouge.
This looks scary to do to a beloved instrument but it will really help get ride of those unsightly gouges.
Step 4: Preparing the Gouges Part Two
Step 5: Preparing the Rosewood
Okay, So I have my rosewood. I took my favorite rotary tool and sanded off some rosewood to make rosewood dust. I captured the dust on a piece of paper as I sanded. You'll need a small pile. But a little does go a long way. One of these pen blanks should last 50 fret gouge jobs.
NOTE: Rosewood is TOXIC!!! Be sure to use a dust mask while working with rosewood. It smells nice, but don't be fooled. People do have allergic reactions to rosewood. So put on your mask! Its also a good idea to put on eye protection while sanding.
Step 6: Pack the Dust
So take your piece of paper with the dust on it and gently tap some dust onto your fret board.
Pack the dust down into the gouges using a closed pocket knife, like I did, or something similar. get as much in as you can. Pack it as tightly as you can.
When you are done it should look like the third picture in this step.
Step 7: Glue Dust
First off, use a thin cyanoacylate glue (super glue). Here is the type I used. SUPER GLUEThis is some heavy duty stuff. Watch your fingers. Put your mask back on! Put on eye protection!
So, drip the glue into the packed dust. The glue will wick down through the dust and the splinters and create the perfect filler for the gouges. As the glue reacts with the dust it might smoke! Don't be alarmed. This type of glue generates heat. Again, watch your fingers, eyes and nose.
Let the glue fully cure. I just let it sit overnight.
Step 8: Sand Sand Sand
When this is done the gouges might be a slightly different color than your original fretboard... but hey the fretboard with be like new again. You can get a lighter color rosewood than your board and then when you apply the glue it might match better. Anyway, the 2nd and 3rd picture in the step make the fillings look much darker than they really are. In person, you have to look closely to see where I filled my frets.
When the sanding is complete, I take a wet cloth and wipe the dust off. Then I take a soft cotton cloth and use it to rub some mineral oil into the entire fret board. I might do this a couple times to let the oil seep into the wood. When complete it should look like pic #2 & #3 in this step.
now to start the re-fretting....
Step 9: Cutting the Fret Wire
I simply laid the wire across the fret slot to be fretted and cut with my nippers right at the edge. You need to cut and shape these wires one at a time because each fret slot is slightly smaller (or bigger depending on which end you start), then the one before. So cut the wire, then proceed to the next couple steps, the come back to this step for the next fret. Get it?
Cut carefully, you only have so much fret wire. Make sure you've estimated correctly! This picture was the easiest way I found.
Step 10: Grinding the Fret Tang
Once the fret is cut to size then I slap it into a vice and take out my favorite rotary tool. I used a grinding bit that is rated for metal.
I grind down the tang of the fret to about 3/16 inch in from each end. This leaves room for the fret end to come to the edge of the neck binding while still allowing the tang to go down into the slot.
I also ground the end of the fret just to nip off the sharp edge. See pic #2.This is optional but it might help you not cut yourself before you shape the frets in a later step.
It should look like pic #3 when complete.
Step 11: Fret! Don't Fret.
I did not use glue on mine. The frets fit nice and tight on their own. If yours don't, you can drizzle a small amount of glue down into the slot. Take care not to get the glue on your fretboard. You can use masking tape to protect your fretboard around your slot.
Now go back to step 9 and repeat until you are completely fretted. then move onto step 12.
Step 12: Shaping the Frets
Note: if you burn under your fret, use caulking or some other type of filler to fill the small gap. Again, I did this a few times but It did not hurt the playability. Maybe you can come up with a better method for this, like hand filing the frets.
Now, you need to put a bevel on the ends of the frets. Again I use the cut off wheel. Most fret bevels are 30 degrees. Many people who re-fret their own instruments over-bevel (I did on my first instrument on two frets.. I was able to pull them out and put a couple new frets in very quickly.... fixed the problem just fine).
So, as you bevel, go slow, work on a 3 or 4 frets at a time to avoid over heating and don't over-bevel.
Now I change the cut off wheel to a sanding disk (pic 2). This will take off small burrs and help to shape and round the fret ends a little more.
Check with you fingers for any sharp parts of the fret. You you find them, carefully sand them blunt.
After the sanding it should look similar to pic #3.
Now I pop off the sanding disc and use a polishing cloth bit and polishing compound (usually comes with the rotary tool). I did not get a picture of this. I have one more guitar to work on, so I will get a picture when I get to polishing those frets. Anyway, with the cloth rotary tool bit and the compound, polish each fret. Pay special attention to the fret ends where you did most of your grinding and sanding so take out and more burrs and polish up.
Step 13: Finishing
I usually clean up the fretboard... and the rest of the guitar at this point. I might rub in some more mineral oil into the fret board again.
Also double check under the frets in case you burned the binding. Use a caulking to fill the small gaps and then clean the surrounding areas.
Also, sometimes the polishing compound leaves residue. Nail polish remover and a cotton swab takes care of this nicely.
Now re-string the thing and get playing! I usually check the instrument and listen for buzzes. If you get a buzz, either your action is not correct or one of the frets is raised up a bit. If it's the action... that's another instructable. If its a raised fret, you can take the strings back off and tap it down better or make a new fret for that position. If this doesn't work you'll need to file your frets. You can get fret files and fret crowing files online at many websites.
I must say though that my instruments worked out just great and sound fantastic. The filled fretboard gouges are like they never existed! The frets came out nice and level. I even checked them with a straight edge and they were fine. Also this is a 'poor man's' instructable and fretting tools are expensive. So I boogered up my binding a bit and maybe burned unto the fret wire a bit, but I fixed these issues cheaply, effectively and easily.
So Good luck and let me know if you have any other ideas that are cheap and don't require specialized tools or equipment!
Thanks for reading.
